Hi Naresh,

Thank you for your interest in Syncfusion products.

Converting an HTML file to PDF

We can able to converting an HTML file to PDF by using FromString(string html, string baseUrl, ImageType type, int width, int height, AspectRatio aspectRatio) method.

Kindly refer the below code snippet which helps to convert an HTML file to PDF.

[c#]

StreamReader reader = new StreamReader(@"..\..\Template.html");
string html = reader.ReadToEnd();
//Create a new pdf document
PdfDocument pdf = new PdfDocument();
//Adds a new pdf page.
PdfPage page = pdf.Pages.Add();
PdfUnitConvertor converter = new PdfUnitConvertor();
float width = converter.ConvertToPixels(page.GetClientSize().Width, PdfGraphicsUnit.Point);

using (HtmlConverter html = new HtmlConverter())
{
//Renders html from the string to image.
PdfMetafile mf = new PdfMetafile(html.FromString(htmlContent,Path.GetFullPath(@"..\..\Template.html"),ImageType.Metafile, (int)width, -1, AspectRatio.KeepWidth) as Metafile);
mf.Quality = 100;

PdfMetafileLayoutFormat format = new PdfMetafileLayoutFormat();
format.Break = PdfLayoutBreakType.FitPage;
format.Layout = PdfLayoutType.Paginate;
//Draws the image.
mf.Draw(page, new PointF(0, 0), format);

// Save the pdf document.
pdf.Save(path);

// Close pdfdocument
pdf.Close(true);
}

Hi Thiru,

Thank you very much for the fast response, I am having an issue with the code sample @ line

using (HtmlConverter html = new HtmlConverter())

The code does not compile it has a curly line underneath it with following description" 'Sync.HtmlConverter.HtmlConverter': type used in a using statement must be implicitly convertible to 'System.IDisposable' " and "The type 'System.Windows.Forms.UserControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'."

Please advice.

Thank you much.

Hi Naresh,

ActiveX control cannot be instantiated Exception

We were able to reproduce the issue which you mentioned here. We can resolve the problem by adding the @Page directive AspCompat="true" attribute to the page where we want to perform HTML to PDF conversions.

<%@ Page Language="C#" AspCompat="true" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" % >

Could you please try the code and let me know if this helps?
